Maxum 2900SCR shifting cable lengths

[magnartbl]

Hi
I have a Maxum 2900 SCR from 2001, twin engine Mercruiser 4.3l v6's and bravo 2 sterndrive.

My port engine has last year had difficulties with the gear shift. I have tried to adjust the shifting cables, without being able to fix the problem, and therefore I now want to exchange the cables.

There are two cables:
- One long shift cable is coming from the controller to the engine.
- One short shift cable goes from the engine to the sterndrive.

I would presume the long shift cable is aboutish 16 feet/192" long. I have no idea about how long the short is, as I cannot follow it behind the engine very well due to the narrow compartment, but my guess would be around 6-7 feet long.

Unfortunately, there are no marking/writings on any of the cable itself. It is totally black giving me no clues. It can have weared away over the years. Also, the engine having issues the cable already seems to have been exchanged once before(!) And, I can't do anything but wonder if that new cable is too long or too short, and might be the rootcause of the issue.
Meaning, pulling it out and measure it might give me a wrong measurement anyhow.

Therefore;

Does anyone know how long these cables should be from factory?
